Hi all,
This patch is part 2 of Bfloat16_t enablement in the ARM back-end.
This new type is constrained using target hooks TARGET_INVALID_CONVERSION,
TARGET_INVALID_UNARY_OP, TARGET_INVALID_BINARY_OP so that it may only
be used
through ACLE intrinsics (will be provided in later patches).
Regression testing on arm-none-eabi passed successfully.
Ok for trunk?
Ok.
Thanks,
Kyrill
Cheers,
Stam
